That’s up dramatically from just a few years ago, when just 8 percent of U.S. Internet users made a phone call online in 2007.

On any given day, about 5 percent of all U.S. Internet users are going online to make phone calls, the survey found, up from 2 percent in 2007.

Certainly, the increase comes as more services become available for Internet users to call online. Earlier this month, Microsoft bought Skype, one of the most popular online phone services, for $8.5 billion. There’s also Google Voice, which became available to the general public last year.
